I. Product Overview

This L-shaped bending shim is made by a single-step forming process of stamping, cutting, and bending from stainless steel thin plate. It features a long strip of flat plate with a 90° bent end, and the plate body is stamped with a cross-shaped non-standard locking hole. The cross holes can be matched with cross screws for firm attachment of parts; the L-shaped bending structure forms a vertical supporting surface, allowing precise adjustment of component assembly gaps. The thin metal sheet also has slight elasticity, providing vibration and loose prevention during operation; the stainless steel base material is corrosion and wear-resistant, suitable for long-term use in humid environments, and the conductive material version can achieve electrical grounding conductivity.

Customizable sheet thickness, bending dimensions, and hole patterns. AllAppearance parameters can be replicated according to customer drawings or physical samples. Both small-scale trial production for new product development and long-term bulk supply can be undertaken. Bending angles and hole position accuracy are inspected and calibrated individually before shipment.

Chapter Two: Core Highlights of Craftsmanship

1. Press-bend one-step forming, angle maintains its shape without rebound
   The entire steel strip is cut and bent in one go, the bending area is treated with stress relief, repeated assembly and disassembly will not cause angular deformation, and the positioning accuracy remains stable for a long time.
2. Cross-shaped non-standard locating holes, excellent locking and anti-rotation effect
   Exclusive cross hollow holes perfectly match with cross screws, ensuring that the washers do not rotate axially after tightening, providing a much stronger assembly than ordinary round hole washers.
3. Thin-section elastic structure, shock absorption and anti-loosening
   Metal thin plates have moderate elasticity, which can compensate for the gap allowance under equipment vibration conditions, preventing loose parts and abnormal noises.
4. Comprehensive burr removal at all edges, assembly without damaging components
   All edges of sheet cutting, inner walls of cross holes, and bending corners are deburred and polished, ensuring no scratching to the circuit board, plastic shell, cables, and other precision components during assembly.
